missing microfeatures in Lout 3.11

[Basile STARYNKEVITCH]

Hello All, 
Hello Jeff,

I'm still missing support of two-sided printing in Lout (some
PostScript printers [with a specific optional hardware tray, eg HP4M
printers] have the ability to print on both sides of a paper
sheet. This is very useful! 

I believe that it is just a matter of adding

%%BeginFeature: *Duplex True
   << /Duplex true >> setpagedevice
%%EndFeature

in the output PostScript. But I don't know exactly where.

On Unix I have a shell script invoking sed:

# file scripts/duplexps
# Time-stamp: <May 13 1997 12:44:14 address@hidden>
# filter to add recto-verso printing
sed -e '/^%%Begin/i\
%%BeginFeature: *Duplex True\
   << /Duplex true >> setpagedevice\
%%EndFeature' $1
## eof $Id: duplexps,v 0.1 1997/05/13 10:44:21 basile Exp $

but it doesn't work well on lout output (the printer does print on
both sides, but the other side is left empty; so in practice it prints 
on only one side, but two times slower [since it reverts each sheet]).



Actually, perhaps the paper sheet & 1 or 2 side printing &
color|monochrome printing should be an option to lout command.

This basically means that 

   lout -a4paper

should behave (i.e. be a short hand) like

   lout 'address@hidden'

and my wish is to have added

   lout -bothsides

as a short hand to

   lout 'address@hidden'


Jeff, if you don't have a 2-side capable postscript printer, I can
test lout for you! Unfortunately, I don't know how to have the 
/Duplex feature added at the right place in the generated output. Very 
probably, it is only a matter of a well designed @SysPrependGraphic!

Another unrelated idea: perhaps it is time to setup a Lout newsgroup
(eg comp.text.lout) but I can't help about it! Does any one know how
much are there Lout users in the world? (hundreds or thousands or
more?)
